I have two objects. Both objects have composite pk.
<class name="parent" table="t_parent">
<composite-id>
<key-property name="effDt" type="date" column="EFF_DT">
</key-property>
<key-property name="group" type="int" column="GROUP"></key-property>
</composite-id>
<many-to-one
name="group"
class="GroupTable"
cascade="none"
outer-join="auto"
>
<column name="EFF_DT" />
<column name="GP_ID"/>
</many-to-one>
</class>
<class name="GroupTable" table="t_group">
<composite-id>
<key-property name="effDt" type="date" column="EFF_DT">
</key-property>
<key-property name="group" type="int" column="GRP_ID"></key-property>
</composite-id>

<property
name="lastUpdateDate"
type="java.util.Date"
column="LST_UPDT"
/>
</class>

When I try to start my server, I get this error:
Repeated column in mapping for entity EFF_DT (should be mapped with insert="false" update="false").
But when I add insert="false" update="false" it complained that insert and update is not in the dtd for < key-property> and <column>

Can someone please help?

Thanks
